The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Waterdrop WD-F13 holds NSF 42 and NSF 372 certifications. NSF 42 covers reduction of aesthetic impurities such as chlorine taste and odor. NSF 372 confirms the filter uses lead-free materials in components that contact the water. Together, these two certifications set a meaningful quality bar for an aftermarket replacement.
At $26.99 for a pack of three, the per-filter cost comes to $9, which is competitive for a Waterdrop-branded certified product. The filter is sized at 10.23 x 3.46 x 5.27 inches and weighs 2.3 lb, giving a clear physical reference for buyers checking compatibility with their refrigerator housing.
The review profile is exceptional: 11,000 ratings at 4.8 stars. Reaching 4.8 stars across a five-figure review count is difficult and signals a filter that consistently meets buyer expectations for fit, flow, and taste performance. For buyers who prefer to let the crowd validate a product before purchasing, the WD-F13 is one of the stronger cases in this category.

Frequently asked questions
What is the practical difference between NSF 42 and NSF 372?
NSF 42 tests the filter's ability to reduce aesthetic impurities, primarily chlorine taste and odor, from drinking water. NSF 372 is not a performance standard for what the filter removes from water. It is a material safety standard that verifies the filter's construction components contain lead-free materials, so the filter itself does not add lead to the water.
Is 4.8 stars across 11,000 reviews unusually high for this product type?
Yes, it is. Most aftermarket refrigerator filters cluster between 4.5 and 4.7 stars at high review counts. Reaching 4.8 across over 11,000 ratings suggests consistent performance with very few significant fit or quality complaints. That said, buyers should still verify compatibility with their specific refrigerator model before purchasing.
How long does each filter last?
No gallons-per-filter capacity is published in the product listing. Most refrigerator replacement filters are designed for approximately six months of regular use, and manufacturers generally recommend using that interval as a default. Actual life depends on water quality and household consumption.
